All questions

Question 1

A phlebotomy technician enters a semi-private room where two patients are present. Patient A's requisition shows 'Margaret Wilson, DOB 04/11/1962, MRN 567890.' Patient B's requisition shows 'Margaret Williams, DOB 04/11/1962, MRN 567891.' Both patients respond when asked 'Are you Margaret?' What is the primary concern in this situation?

  1. The identical birthdates suggest possible twins requiring additional family history verification
  2. The similar names and identical birthdates create high risk for patient misidentification (correct answer)
  3. Both patients responding indicates hearing impairment requiring alternative identification methods
  4. The room assignment error should be reported since patients with similar names shouldn't share rooms
Explanation: The combination of very similar names (Wilson/Williams) and identical birthdates creates an extremely high-risk situation for patient misidentification. This requires extra careful verification of all identifiers including checking wristbands and having patients state their full names. Choice A incorrectly assumes family relationship. Choice C misinterprets the response issue. Choice D addresses room assignment rather than identification procedures.

Question 2

A phlebotomy technician arrives at room 214 to collect blood from patient Maria Gonzalez, DOB 03/15/1985. The patient states her name as 'Maria Rodriguez' and confirms the birthdate. The patient's wristband shows 'Maria G. Rodriguez, DOB 03/15/1985, MRN 456789.' The requisition form lists 'Maria Gonzalez, DOB 03/15/1985, MRN 456789.' What should the technician do next?

  1. Proceed with the collection since the birthdate and medical record number match exactly between all sources
  2. Contact the nursing station to verify the patient's legal name and resolve the discrepancy before proceeding (correct answer)
  3. Ask the patient to provide photo identification to confirm her current legal name before collection
  4. Document the name discrepancy in the collection notes and proceed since two identifiers match
Explanation: When there is any discrepancy in patient identifiers, the technician must resolve it before proceeding with collection. The name inconsistency between the requisition (Gonzalez) and wristband (Rodriguez) creates uncertainty about patient identity. Contacting the nursing station allows verification through official hospital records. Choice A ignores the name discrepancy. Choice C may not resolve which name is correct in the medical record. Choice D is unsafe as it proceeds despite unresolved identification issues.

Question 3

A phlebotomy technician is collecting from pediatric patient 'Ashley Chen, DOB 06/22/2018.' The child's wristband reads 'Ashley Chen, DOB 06/22/2018, MRN 234567.' The mother confirms 'Yes, this is Ashley Chen, born June 22nd, 2018.' However, the requisition form shows 'Ashley Chen, DOB 06/22/2016, MRN 234567.' Which aspect of this situation requires immediate attention?

  1. The medical record number must be verified independently since it appears on both documents
  2. The birthdate discrepancy between requisition and wristband must be resolved before collection (correct answer)
  3. The mother's verbal confirmation should be documented as the third identifier verification method
  4. The child's physical appearance should be assessed to determine which birthdate seems correct
Explanation: The two-year birthdate discrepancy between the requisition (2016) and wristband (2018) represents a critical identification error that must be resolved immediately. This could indicate wrong patient orders or incorrect wristband placement. Choice A overlooks the birthdate issue. Choice C incorrectly assumes the collection should proceed. Choice D is inappropriate as physical assessment cannot reliably determine age differences in children.

Question 4

A phlebotomy technician is collecting from an outpatient who presents with a requisition showing 'James Park, DOB 01/20/1988, ordering physician Dr. Martinez.' The patient states his name as 'James Park' and birthdate as 'January 20th, 1988.' However, the patient has no hospital wristband since this is an outpatient draw. What additional verification is required?

  1. Request photo identification to serve as the second required identifier for outpatient collections (correct answer)
  2. Have the patient sign a verification form confirming his identity and contact information
  3. Contact Dr. Martinez's office to confirm the patient's appointment and identity verification
  4. Ask the patient to provide his address or phone number as listed in the medical records
Explanation: Outpatient collections require two patient identifiers when no wristband is available. With name and birthdate already confirmed, photo identification serves as the appropriate second identifier. Choice B creates documentation but doesn't provide verification. Choice C is unnecessarily time-consuming for routine outpatient draws. Choice D provides additional information but may not definitively confirm identity.

Question 5

A phlebotomy technician needs to collect blood from patient 'David Lee, DOB 11/03/1985, MRN 456123.' Upon entering the room, the technician finds the patient wearing a wristband reading 'David Lee, DOB 11/30/1985, MRN 456123.' The patient confirms 'David Lee, November 3rd, 1985.' Which element of this scenario requires the most careful attention?

  1. The patient's verbal confirmation contradicts his wristband, suggesting possible confusion about his birthdate
  2. The day-of-month discrepancy could indicate a data entry error when the wristband was created
  3. The matching medical record numbers suggest the discrepancy is minor and collection can proceed safely
  4. The wristband shows November 30th while requisition and patient state November 3rd, indicating a wristband error (correct answer)
Explanation: Patient identification in phlebotomy requires absolute accuracy across all identifiers before any blood collection can proceed. When you encounter discrepancies between patient identification sources, you must identify which source contains the error and resolve it completely before drawing blood. In this scenario, you have three sources of identification: the requisition (November 3rd), the patient's verbal confirmation (November 3rd), and the wristband (November 30th). Two sources agree on November 3rd while only the wristband shows November 30th. This pattern clearly indicates the wristband contains incorrect information, making option D correct—the wristband error must be addressed before proceeding. Option A incorrectly suggests the patient is confused, but the patient's verbal confirmation actually matches the requisition, not the wristband. Option B focuses on the mechanism of how the error occurred (data entry) rather than identifying which source is wrong—while this might explain the discrepancy, it doesn't address the core identification problem. Option C is dangerous because it suggests proceeding with collection despite unresolved discrepancies; matching MRNs don't override the need for all identifiers to be accurate. Remember this key principle for the CPT exam: Never proceed with blood collection when any patient identifier doesn't match. Always identify which source contains the error by comparing all available information sources. When multiple sources agree against one source (as with the birth dates here), the single disagreeing source typically contains the error and must be corrected first.

Question 6

During identification verification, an elderly patient with dementia repeatedly states her name as 'Betty' when asked. Her wristband reads 'Elizabeth Johnson, DOB 09/30/1940, MRN 678901,' and the requisition matches exactly. A family member present confirms 'She's always gone by Betty, but her legal name is Elizabeth.' How should the technician proceed?

  1. Accept 'Betty' as adequate verbal confirmation since the family member verified the nickname usage
  2. Require the patient to state 'Elizabeth' specifically to ensure proper identification protocol compliance
  3. Use the wristband and requisition match as sufficient identification given the patient's cognitive condition (correct answer)
  4. Document the nickname preference and verify the birthdate as an alternative identification method
Explanation: When patients have cognitive impairments affecting their ability to provide reliable verbal identification, matching wristband and requisition information becomes the primary identification method. The family member's explanation about the nickname supports this approach. Choice A relies too heavily on potentially unreliable verbal confirmation. Choice B is impractical for patients with dementia. Choice D doesn't address the fundamental identification approach needed for cognitively impaired patients.

Question 7

While verifying patient identity, a phlebotomy technician notices the requisition lists 'Robert Smith Jr., DOB 12/08/1975, MRN 345678.' The patient's wristband shows 'Robert Smith, DOB 12/08/1975, MRN 345678.' When asked to state his name, the patient responds 'Robert Smith Junior.' What should the technician conclude?

  1. This represents adequate identification since the patient confirmed the 'Junior' designation verbally
  2. The missing 'Jr.' on the wristband creates insufficient identification requiring resolution before collection
  3. The name variation is acceptable since birthdate and medical record number match exactly
  4. Additional verification is needed since three different name formats have been presented (correct answer)
Explanation: Three different name presentations exist: 'Robert Smith Jr.' (requisition), 'Robert Smith' (wristband), and 'Robert Smith Junior' (verbal). While these likely refer to the same person, the inconsistency in name formatting requires verification to ensure proper patient identification. Choice A overlooks the documentation discrepancies. Choice B focuses only on the wristband issue. Choice C ignores the potential for identification errors when multiple name formats exist.

Question 8

During patient identification, a phlebotomy technician finds that an unconscious emergency department patient has no wristband. The requisition shows 'John Doe #3, DOB unknown, MRN 789012.' A family member present states the patient is 'Johnny Thompson, born May 5th, 1990.' What is the most appropriate action?

  1. Use the family member's information to create a temporary identification band and proceed with collection
  2. Collect the specimen using the 'John Doe #3' identifier and document the family information separately
  3. Contact the emergency department staff to establish proper patient identification before any collection (correct answer)
  4. Request the family member provide photo identification of the patient before proceeding with collection
Explanation: For unconscious patients without proper identification bands, the phlebotomy technician must work with clinical staff to establish positive identification before collection. Emergency department protocols exist for identifying unknown patients. Choice A is unsafe as family information hasn't been verified. Choice B proceeds with inadequate identification. Choice D won't resolve the identification system requirements for the hospital's records.

Question 9

During a busy morning shift, a phlebotomy technician has requisitions for three patients: 'Jennifer Adams DOB 02/14/1990 MRN 123456,' 'Jennifer Adams DOB 02/14/1991 MRN 123457,' and 'Jennifer Adams DOB 02/14/1992 MRN 123458.' All three patients are located on the same nursing unit. What approach best ensures accurate patient identification?

  1. Verify each patient's wristband matches their specific requisition and have them state their complete birthdate (correct answer)
  2. Collect specimens in MRN order to maintain systematic tracking and reduce identification errors
  3. Ask nursing staff to temporarily separate the patients to different rooms during collection procedures
  4. Use photo identification as an additional identifier for all three patients given the high-risk situation
Explanation: With three patients having identical names and consecutive birthdates, meticulous verification of wristband-to-requisition matching plus verbal birthdate confirmation provides the most reliable identification. The one-year birthdate differences make this verification critical. Choice B addresses workflow but not identification accuracy. Choice C is impractical in most hospital settings. Choice D adds verification but wristband confirmation remains the primary need.

Question 10

While performing patient identification, a phlebotomy technician discovers that the patient's wristband shows 'Mary Johnson, DOB 05/15/1979, MRN 789123,' but the requisition shows 'Mary Johnson, DOB 05/15/1997, MRN 789123.' The patient appears to be middle-aged and states 'I'm Mary Johnson, born May 15th, 1979.' What factor makes this situation particularly concerning?

  1. The 18-year birthdate discrepancy suggests possible identity theft or medical record fraud
  2. Laboratory results could be filed in the wrong patient record due to the birthdate error (correct answer)
  3. The patient's apparent age contradicts the 1997 birthdate, indicating a transcription error
  4. Different birthdates may indicate separate medical record numbers should have been assigned
Explanation: The primary concern is that laboratory results could be posted to the wrong patient's medical record if the birthdate discrepancy isn't resolved. Since the MRN matches but birthdates differ, the laboratory information system might file results incorrectly. Choice A overstates the likely cause. Choice C focuses on obvious visual cues rather than systematic concerns. Choice D misunderstands how MRNs are assigned.
